ICA Securing Workloads Practice Question
A service 'orders' requires a specific AuthorizationPolicy that allows GET requests only from the 'frontend' service while denying all other methods. Which configuration is correct?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set 'action: ALLOW', 'rules: [{from: [{source: {principals: [cluster.local/ns/default/sa/frontend]}}], to: [{operation: {methods: [GET]}}]}]'.
The AuthorizationPolicy should specify the 'GET' method in the 'rules' section and match the 'frontend' principal in the 'from' source block.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create an EnvoyFilter to intercept and drop requests.
Why it's wrong here
While possible, using an AuthorizationPolicy is the standard and recommended way to handle this.
- ✗
Use a PeerAuthentication policy to filter based on HTTP methods.
Why it's wrong here
PeerAuthentication does not support filtering by HTTP methods.
- ✓
Set 'action: ALLOW', 'rules: [{from: [{source: {principals: [cluster.local/ns/default/sa/frontend]}}], to: [{operation: {methods: [GET]}}]}]'.
Why this is correct
This policy correctly restricts access to the GET method for the specified service account.
- ✗
Set 'action: DENY', 'rules: [{to: [{operation: {methods: [POST, PUT, DELETE]}}]}]'.
Why it's wrong here
Using DENY is less secure than an ALLOW-by-default or explicit ALLOW policy for granular control.
